To all whom may cone-m Be it k110i n that I, Micireriii a citizen of the United States, Bur ette, in the count of Hand an. of Souin Dakota, have invented n usei'ui Device to Trim Horses which the following is e specificai-i The device forming the subject limiter 0i applicatiom is aciupterl primarily, although not exclusively to be employed the 'irinnning of lierses' hoof s and one object of the invention is to pi vicle hoof trimmer which will operate :ioiselessiy, A furrher object of the invention pro vide hoof trimnier having means I lubricating the hoof trimming tool.

Another object of the invention is to provicle a clevice 01" 'he by m above nientiei l which may be traiisicrlned into a farmer syringe.

Secured to the outer end of the piston rod 16 is a relatively heavy head 18, provided in its under face with a recess 19 receiving a resilientbufier 20.

In practical operation, the closure plug the relatively hcavy head 18 will be received by the cap 10, an impulse being thereby impart-ed to the casing which will serve to drive the tool 9 into and through the hoof of the horse. Qbviously, the butter 20, en-

\ gagingthe cap 10, will permit the structure to operate noiselessly, a frightening ofthc horse being thereby avoided.

in order that the head 18 may exercise its full efiiciency as a driving element, it is desirable that; the head 17 should cause a minimum compression within the casing. To this end, the nut n'ianipulated so as to expand the piston head suliiciently to create a very slight compression within the 'cas'iug, only sutiicient compression being generated to force the oil out o't the ducts or grooves 28. I

In practice, it is necessary that the piston head 17 have a slight and almost imperceptible bearing upon the interior of the member 1 of the casin Under the circumstance above pointed out, when the plunger is depressed, 2. small quantity of oil will flow out of the grooves 23 'upon each stroke of the plunger, the cutting tool 9 being there-. by lubricated.

In that. form of the invention. which appears in Fig. 8, the operation above outlined takes place, the oil flowing outwardly "through the openings 27.

As a useful feature, which however, can not be claimed, it is to be noted that it is possible to remove the secondary part 2 from the collar 3 and to replacethe secondary part by a nozzle 21, as shown in Fig. 2,
